Paragon HFS + for Windows 8.0 will not instal

i have successfully installed Paragon HFS+, but this time i can't get it to install. i downloaded the trial installer for Windows 7 64-bit, i started the installer, put in my license info, and the installer starts. only problem is that it starts saying that its "rolling back the action" or something. at the end, a dialog box tells me that something is preventing HFS from installing.

I have the exact same problem :/ the most annoying thing tho, is that after I tried to install Paragon HFS, the apple driver isn't working aswell. When I start my computer up in win7 I now have to try to install paragon HFS, which then rolls back the driver, because I can't get it to install. First then do I see my Mac partition again. So it's all very strange.

I tried the log, but it's kinda unreadable to the naked eye, it says my serial is wrong, but I'm installing the trial so I don't get it. Hope the OP can post his log.

EDIT: I'm on a early 2011 15" MBP just in case the OP has same model.?!?

Thanks for the reply. However...
The link you provided is not working.
The knowledge base link on the Paragon site is also not working.
The community forum link comes back here.
The support services link states that complimentary support is free for 30 days after purchase and is then $99.95 per incident. Version 9 is not a free upgrade. They offer a 30% discount for competitive update but nothing is mentioned for owners of previous versions.
They are doing this wrong.

I contacted customer support and they provided me with a serial for version 9 once I told them I could not get version 8 to install. However there seems to be some serious issues with version 9 right now. After I installed it, it corrupted my osx partition and I could no longer boot to it. I had to restore from a backup to be able get back into osx. You and everyone else thinking of buying/installing version 9 needs to wait until this bug is corrected unless you like restoring your hard drives.

Now that the version check looks like VersionNT >= 601 you can save it named as is.
HxD creates a .bak from the original file. After this procedure you can install Paragon HFS+ 8.0.1 like before Win7 SP1.
